E. Schieffelin Mining Clinometer & Mining Keys
For your consideration is this original, M. Attwood's Mining Clinometer manufactured by A. Lietz Company, reported to have been owned by Ed Schieffelin (1847-1897) in the early 1890s and original keys from the Foundry Building of the Tombstone Mining & Milling Company. Melville Attwood was born in England in 1813 and emigrated to the United States in 1852, at the age of 39. He arrived at the Port of New York on May 31, and his occupation was listed as Mining Engineer. Adolph Lietz was born in 1860 in the northern German city of Leubeck, which is a prominent harbor city. Lietz emigrated to America in 1879 and resided in San Francisco, where he worked for several scientific instrument companies before purchasing Carl Rahsskopff's firm, which he renamed A. Lietz & Co. in 1882. A mining clinometer measures the angle of sloped mine passages, shafts, and ore veins. It's essentially an instrument used to determine the dip (angle of inclination) and strike (horizontal direction) of geological formations, including ore deposits. This data is crucial for planning and executing mining operations. This one was reported to have been owned by Ed Schieffelin, the founder of Tombstone and the Lucky Cuss Mine in Tombstone. Edward Lawrence Schieffelin (1847-1897) was an American prospector and Indian Scout who discovered silver in the Arizona Territory, which led to the establishment of Tombstone. He formed a handshake agreement with his brother Al and mining engineer Richard Gird that resulted in millions of dollars of wealth for all three men. Throughout Tombstone's mining history, the mines generated around US$85,000,000 in silver. It shows a compass and two levels for making calculations. It comes in its original leather case and shows fair condition overall with wear present to the tool and the leather case. One piece of glass from the tool does not fit into its designated spot. There are four keys from the Foundry Building of the Tombstone Mining & Milling Company, which were purchased from the Wells, Fargo Museum in Tombstone. Only one key is marked reading, "T & B FDY. Co.". The pieces show good condition overall with slight wear present, and no signs of major damage. The tool measures 6 3/8" L x 3" W x 1/2" D. The keys measure from 1 3/4" L x 5/8" W to 2 3/4" L x 7/8" W. They have a collective weight of 9 ounces. Provenance: From the Tombstone Western Heritage Museum in Tombstone, Arizona. M31 TT99
